It is a house built in Yokohama-shi, Kanagawa.
There was it in the vicinity of the top of a residential area developed land for by a slant ground and did main space such as the living in the second floor because a view was good at the second floor level.
At first I thought while considering privacy because it was a residential area because I discovered a concept of how to open window that light and wind entered wealthily.
Not a simple quadrangle, I planned a ground plan, an opening on a principle I repeated an irregularity, and to make each corner of the flat mask which became octagonal an opening. I suppress the opening side of the corner small and I am slightly bigger and take it boldly and create the relations with the outdoors variously in one house.
